Product liability law addresses the accountability of manufacturers, distributors, or sellers for injuries caused by defective or dangerous products. It hinges on three main types of defects: design flaws, manufacturing defects, or inadequate warnings/instructions. Under this law, a consumer can seek compensation for damages like medical expenses, lost income, or pain and suffering if they can prove that the product was defective, the defect made the product unreasonably dangerous, and the defect directly caused the injury or damage. Liability can be established through theories like strict liability, where fault doesn't need to be proven, negligence, or breach of warranty. This area of law varies by state but generally aims to ensure products are safe for their intended use, with the burden often on the producer to demonstrate they took reasonable steps to avoid harm.
